# Notification.Builder

`public static class Notification.Builder`
`extends Object` ``

java.lang.Object
↳ | android.app.Notification.Builder

Builder class for `Notification` objects. Provides a convenient way to set the various fields of a `Notification` and generate content views using the platform's notification layout template. If your app supports versions of Android as old as API level 4, you can instead use `NotificationCompat.Builder`, available in the Android Support library.

Example:

     Notification noti = new Notification.Builder(mContext)
             .setContentTitle("New mail from " + sender.toString())
             .setContentText(subject)
             .setSmallIcon(R.drawable.new_mail)
             .setLargeIcon(aBitmap)
             .build();

## Public constructors

### Builder

    public Builder (Context context,
                    String channelId)

Constructs a new Builder with the defaults:

Parameters
`context` | `Context`: A `Context` that will be used by the Builder to construct the RemoteViews. The Context will not be held past the lifetime of this Builder object.
`channelId` | `String`: The constructed Notification will be posted on this `NotificationChannel`. To use a NotificationChannel, it must first be created using `NotificationManager#createNotificationChannel`.

### Builder

    public Builder (Context context)

This constructor is deprecated.
use `Builder(android.content.Context, java.lang.String)` instead. All posted Notifications must specify a NotificationChannel Id.

Parameters
`context` | `Context`

## Public methods

### addAction

    public Notification.Builder addAction (int icon,
                    CharSequence title,
                    PendingIntent intent)

This method is deprecated.
Use `addAction(android.app.Notification.Action)` instead.

Add an action to this notification. Actions are typically displayed by the system as a button adjacent to the notification content.

Every action must have an icon (32dp square and matching the Holo Dark action bar visual style), a textual label, and a `PendingIntent`.

A notification in its expanded form can display up to 3 actions, from left to right in the order they were added. Actions will not be displayed when the notification is collapsed, however, so be sure that any essential functions may be accessed by the user in some other way (for example, in the Activity pointed to by `Notification.contentIntent`).

Parameters
`icon` | `int`: Resource ID of a drawable that represents the action.
`title` | `CharSequence`: Text describing the action.
`intent` | `PendingIntent`: PendingIntent to be fired when the action is invoked.

Returns
`Notification.Builder` |

### addAction

    public Notification.Builder addAction (Notification.Action action)

Add an action to this notification. Actions are typically displayed by the system as a button adjacent to the notification content.

Every action must have an icon (32dp square and matching the Holo Dark action bar visual style), a textual label, and a `PendingIntent`.

A notification in its expanded form can display up to 3 actions, from left to right in the order they were added. Actions will not be displayed when the notification is collapsed, however, so be sure that any essential functions may be accessed by the user in some other way (for example, in the Activity pointed to by `Notification.contentIntent`).

Parameters
`action` | `Notification.Action`: The action to add.

Returns
`Notification.Builder` | This value cannot be `null`.

### addExtras

    public Notification.Builder addExtras (Bundle extras)

Merge additional metadata into this notification.

Values within the Bundle will replace existing extras values in this Builder.

Parameters
`extras` | `Bundle`

Returns
`Notification.Builder` | This value cannot be `null`.

See also:

- `Notification.extras`

### addPerson

    public Notification.Builder addPerson (String uri)

This method is deprecated.
use `addPerson(android.app.Person)`

Add a person that is relevant to this notification.

Depending on user preferences, this annotation may allow the notification to pass through interruption filters, if this notification is of category `Notification.CATEGORY_CALL` or `Notification.CATEGORY_MESSAGE`. The addition of people may also cause this notification to appear more prominently in the user interface.

The person should be specified by the `String` representation of a `ContactsContract.Contacts.CONTENT_LOOKUP_URI`.

The system will also attempt to resolve `mailto:` and `tel:` schema URIs. The path part of these URIs must exist in the contacts database, in the appropriate column, or the reference will be discarded as invalid. Telephone schema URIs will be resolved by `ContactsContract.PhoneLookup`. It is also possible to provide a URI with the schema `name:` in order to uniquely identify a person without an entry in the contacts database.

Parameters
`uri` | `String`: A URI for the person.

Returns
`Notification.Builder` |

See also:

- `Notification.EXTRA_PEOPLE`

### addPerson

    public Notification.Builder addPerson (Person person)

Add a person that is relevant to this notification.

Depending on user preferences, this annotation may allow the notification to pass through interruption filters, if this notification is of category `Notification.CATEGORY_CALL` or `Notification.CATEGORY_MESSAGE`. The addition of people may also cause this notification to appear more prominently in the user interface.

A person should usually contain a uri in order to benefit from the ranking boost. However, even if no uri is provided, it's beneficial to provide other people in the notification, such that listeners and voice only devices can announce and handle them properly.

Parameters
`person` | `Person`: the person to add.

Returns
`Notification.Builder` | This value cannot be `null`.

See also:

- `Notification.EXTRA_PEOPLE_LIST`

### build

    public Notification build ()

Combine all of the options that have been set and return a new `Notification` object. If this notification has `BubbleMetadata` attached that was created with a shortcutId a check will be performed to ensure the shortcutId supplied to bubble metadata matches the shortcutId set on the notification builder, if one was set. If the shortcutId's were specified but do not match, an exception is thrown here.

Returns
`Notification` | This value cannot be `null`.

This method is deprecated.
use `NotificationChannel#enableLights(boolean)` instead.

Set the desired color for the indicator LED on the device, as well as the blink duty cycle (specified in milliseconds). Not all devices will honor all (or even any) of these values.

Parameters
`argb` | `int`
`onMs` | `int`
`offMs` | `int`

Returns
`Notification.Builder` |

    public Notification.Builder setLocalOnly (boolean localOnly)

Set whether or not this notification should not bridge to other devices.

Some notifications can be bridged to other devices for remote display. This hint can be set to recommend this notification not be bridged.

Parameters
`localOnly` | `boolean`

Returns
`Notification.Builder` | This value cannot be `null`.

### setLocusId

    public Notification.Builder setLocusId (LocusId locusId)

Sets the `LocusId` associated with this notification.

This method should be called when the `LocusId` is used in other places (such as `ShortcutInfo` and `ContentCaptureContext`) so the device's intelligence services can correlate them.

Returns
`Notification.Builder` | This value cannot be `null`.

### setNumber

    public Notification.Builder setNumber (int number)

Sets the number of items this notification represents. May be displayed as a badge count for Launchers that support badging.

`number` | `int`

Returns
`Notification.Builder` | This value cannot be `null`.

### setOngoing

    public Notification.Builder setOngoing (boolean ongoing)

Set whether this is an "ongoing" notification. Ongoing notifications cannot be dismissed by the user, so your application or service must take care of canceling them. They are typically used to indicate a background task that the user is actively engaged with (e.g., playing music) or is pending in some way and therefore occupying the device (e.g., a file download, sync operation, active network connection).

Parameters
`ongoing` | `boolean`

Returns
`Notification.Builder` | This value cannot be `null`.

See also:

- `Notification.FLAG_ONGOING_EVENT`

Parameters
`onlyAlertOnce` | `boolean`

Returns
`Notification.Builder` | This value cannot be `null`.

See also:

- `Notification.FLAG_ONLY_ALERT_ONCE`

`pri` | `int`: Value is `Notification.PRIORITY_DEFAULT`, `Notification.PRIORITY_LOW`, `Notification.PRIORITY_MIN`, `Notification.PRIORITY_HIGH`, or `Notification.PRIORITY_MAX`

Returns
`Notification.Builder` |

See also:

- `Notification.priority`

### setProgress

    public Notification.Builder setProgress (int max,
                    int progress,
                    boolean indeterminate)

`indeterminate` | `boolean`

Returns
`Notification.Builder` | This value cannot be `null`.

### setPublicVersion

    public Notification.Builder setPublicVersion (Notification n)

Supply a replacement Notification whose contents should be shown in insecure contexts (i.e. atop the secure lockscreen). See `Notification.visibility` and `Notification.VISIBILITY_PUBLIC`.

Parameters
`n` | `Notification`: A replacement notification, presumably with some or all info redacted.

Returns
`Notification.Builder` | The same Builder. This value cannot be `null`.

### setRemoteInputHistory

    public Notification.Builder setRemoteInputHistory (CharSequence[] text)

Set the remote input history. This should be set to the most recent inputs that have been sent through a `RemoteInput` of this Notification and cleared once the it is no longer relevant (e.g. for chat notifications once the other party has responded). The most recent input must be stored at the 0 index, the second most recent at the 1 index, etc. Note that the system will limit both how far back the inputs will be shown and how much of each individual input is shown.

Note: The reply text will only be shown on notifications that have least one action with a `RemoteInput`.

Parameters
`text` | `CharSequence`

Returns
`Notification.Builder` | This value cannot be `null`.

### setSettingsText

    public Notification.Builder setSettingsText (CharSequence text)

Provides text that will appear as a link to your application's settings.

This text does not appear within notification `Style` but may appear when the user uses an affordance to learn more about the notification. Additionally, this text will not appear unless you provide a valid link target by handling `Notification.INTENT_CATEGORY_NOTIFICATION_PREFERENCES`.

This text is meant to be concise description about what the user can customize when they click on this link. The recommended maximum length is 40 characters.

Returns
`Notification.Builder` | This value cannot be `null`.

### setShortcutId

    public Notification.Builder setShortcutId (String shortcutId)

From Android 11, messaging notifications (those that use `MessagingStyle`) that use this method to link to a published long-lived sharing shortcut may appear in a dedicated Conversation section of the shade and may show configuration options that are unique to conversations. This behavior should be reserved for person to person(s) conversations where there is a likely social obligation for an individual to respond.

For example, the following are some examples of notifications that belong in the conversation space:

- 1:1 conversations between two individuals
- Group conversations between individuals where everyone can contribute

And the following are some examples of notifications that do not belong in the conversation space:

- Advertisements from a bot (even if personal and contextualized)
- Engagement notifications from a bot
- Directional conversations where there is an active speaker and many passive individuals
- Stream / posting updates from other individuals
- Email, document comments, or other conversation types that are not real-time

Additionally, this method can be used for all types of notifications to mark this notification as duplicative of a Launcher shortcut. Launchers that show badges or notification content may then suppress the shortcut in favor of the content of this notification.

If this notification has `BubbleMetadata` attached that was created with a shortcutId a check will be performed to ensure the shortcutId supplied to bubble metadata matches the shortcutId set here, if one was set. If the shortcutId's were specified but do not match, an exception is thrown.

Parameters
`shortcutId` | `String`: the `ShortcutInfo#getId()` of the shortcut this notification is linked to

Returns
`Notification.Builder` | This value cannot be `null`.

See also:

- `Notification.BubbleMetadata.Builder.Builder(String)`

### setShowWhen

    public Notification.Builder setShowWhen (boolean show)

Control whether the timestamp set with `setWhen` is shown in the content view. For apps targeting `Build.VERSION_CODES.N` and above, this defaults to `false`. For earlier apps, the default is `true`.

Parameters
`show` | `boolean`

Returns
`Notification.Builder` | This value cannot be `null`.

### setSmallIcon

    public Notification.Builder setSmallIcon (int icon,
                    int level)

Parameters
`icon` | `int`: A resource ID in the application's package of the drawable to use.
`level` | `int`: The level to use for the icon.

Returns
`Notification.Builder` | This value cannot be `null`.

See also:

- `Notification.icon`
- `Notification.iconLevel`

### setSmallIcon

    public Notification.Builder setSmallIcon (int icon)

Set the small icon resource, which will be used to represent the notification in the status bar. The platform template for the expanded view will draw this icon in the left, unless a `large icon` has also been specified, in which case the small icon will be moved to the right-hand side.

Parameters
`icon` | `int`: A resource ID in the application's package of the drawable to use.

Returns
`Notification.Builder` | This value cannot be `null`.

See also:

- `Notification.icon`

`Notification.Builder` | This value cannot be `null`.

See also:

- `Notification.icon`

### setSortKey

    public Notification.Builder setSortKey (String sortKey)

Set a sort key that orders this notification among other notifications from the same package. This can be useful if an external sort was already applied and an app would like to preserve this. Notifications will be sorted lexicographically using this value, although providing different priorities in addition to providing sort key may cause this value to be ignored.

This sort key can also be used to order members of a notification group. See `setGroup(String)`.

Parameters
`sortKey` | `String`

Returns
`Notification.Builder` | This value cannot be `null`.

See also:

- `String.compareTo(String)`

### setSound

    public Notification.Builder setSound (Uri sound,
                    AudioAttributes audioAttributes)

use `NotificationChannel#setSound(Uri, AudioAttributes)` instead.

Set the sound to play, along with specific `AudioAttributes` to use during playback.

Parameters
`sound` | `Uri`
`audioAttributes` | `AudioAttributes`

Returns
`Notification.Builder` |

See also:

- `Notification.sound`

### setSound

    public Notification.Builder setSound (Uri sound)

This method is deprecated.
use `NotificationChannel#setSound(Uri, AudioAttributes)` instead.

Set the sound to play. It will be played using the `default audio attributes` for notifications.

Parameters
`sound` | `Uri`

Returns
`Notification.Builder` |

### setSound

    public Notification.Builder setSound (Uri sound,
                    int streamType)

`style` | `Notification.Style`: Object responsible for modifying the notification style.

Returns
`Notification.Builder` | This value cannot be `null`.

### setSubText

    public Notification.Builder setSubText (CharSequence text)

This provides some additional information that is displayed in the notification. No guarantees are given where exactly it is displayed.

This information should only be provided if it provides an essential benefit to the understanding of the notification. The more text you provide the less readable it becomes. For example, an email client should only provide the account name here if more than one email account has been added.

As of `Build.VERSION_CODES.N` this information is displayed in the notification header area. On Android versions before `Build.VERSION_CODES.N` this will be shown in the third line of text in the platform notification template. You should not be using `setProgress(int, int, boolean)` at the same time on those versions; they occupy the same place.

Parameters
`text` | `CharSequence`

Returns
`Notification.Builder` | This value cannot be `null`.

### setTicker

    public Notification.Builder setTicker (CharSequence tickerText,
                    RemoteViews views)

Returns
`Notification.Builder` | This value cannot be `null`.

### setUsesChronometer

    public Notification.Builder setUsesChronometer (boolean b)

Show the `Notification#when` field as a stopwatch. Instead of presenting `when` as a timestamp, the notification will show an automatically updating display of the minutes and seconds since `when`.
